Appication filed September 18, 1916. Serial No.

To all whom it'ma i concern:

Be it known that I, HOWARD H. CRAWFORD, a citizen of the United States of America residing at Detroit, in the county of Wayne and State of Michigan, have invented cer tain new and useful Improvements in Radiator-Shields, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to temperature controlling'devices for radiators, and has particular reference to constructions adapted for use either in the original installation or as a replacement.

In the present state of the art, radiators have been provided with shutters for controlling the volume of air passing through the radiator core. These shutters have, however, been mounted as adjuncts to the radiator, and are objectionable in that they mar the appearance and change the standard lines of the machine. It is the object of the present invention to avoid this objection, and to this end the invention comprises the novel combination of the shutters with the shell which incloses the radiator core. Heretofore radiators have been provided with pressed sheet-metal shells which form the outer finish, completelysurrounding the radiator core but not thereof. Such shells'are usually provided with a front face concealing the top and bottom headers and edges of the core, but having an open panel for exposing the air and water tubes. \Vith my IIDPIOX'Bd construction I make use of a shell of the same extended outward sufficiently in advance of the front face of the air and water tubes to receive and provide clearance for the operation of shutters. The are mounted within the shell and are preferably so arranged that in closed position they present a substantially flat face parallel to the plane of the front face of the shell, are arranged at right angles and fully expose the air and water tubes.

In the drawings:

Figure 1 is a front elevation of the construction embodying my invention;

Fig. 2 is a perspective view showing the inner side of the shell and shutters mounted therein in closed position;

Fig. 3 is a horizontal section; and

Fig. 4 is a vertical section.

a structural part while in opened position they Patented sept. a, mac. 120,863.

My improved construction is applicable tion comprises a shell A, preferably formed of pressed sheet-metal, and having the inte-- gral side flanges B and front face C, the latter having the open panel D. On the opposite sides of the front and on'the inner face thereof are mounted bearings E, preferably in the form of a channel bar having a fiber filler F, apertured for receit'ing the pintles G of the shutters H. These pintles are preferably the end portions of hinge rods I extending the full length of the shut ters and preferably at one edge thereof which is looped around the rod, while the opposite edge is adapted to underlap the adjacent rod. Each shutter is also provided with a lug J having a pintle K engaging an actuating bar L struction to the bars E. M is a bell-crank lever fnlcrumed upon the shell and with the bar L.-

lVhere the construction is designed for a replacement, the shell may be formed either of the same lines as the original or of changed lines, but in each case the depth is increased a sufficient amount to provide for the operation of the shutters in front of the core. In the same manner, where the device is designed for original installation increased depth of shell is provided, but otherwise the lines remain standard. The WhOiP, construction is independent of the core and can be removed or replaced without disturbing the latter, while the space between the sides of the shell and the core provides clearance for the. operating mechanism.

Any suitable construction of radiator core may be employed, such as indicated in dotted lines in Figs 3 and 4.

\Vhat I claim as my invention is 1. The combination with a radiator core, of a shell forming the regular outer finishing piece for said core, having an open panel .for exposing the air and water tubes and bei'ng extended beyond the front plane of the same, and shutters mounted andoperable within said shell between the front face thereof and the front face of the core.

2. The combination with a radiator core,

of a shell forming the regular outer finish-' similar in con-' connected by a pivotal link N inner side of the rang v of a shell forming ing piece for ing piece for said core, having its front face in a plane spaced from the front face of the core, shutters mounted within said shell and operable in the space between the front face thereof and the front face of the core, and operating mechanism for said shutters ared between the side of the shell and the side of the core.

3. The combination with a radiator core, of a shell forming the regular outer finishing piece for said core formed of pressed sheet-metal, having affront face with an open panel and sides extending rearward therefrom, the depth of said sides being suf-' ficient to space the front face from the front face of the core, and shutters mounted on the inner face of the front of said shell adapted in one position to'close said open panel and also to swing in the space between the shell and core to open said panel.

4. The combination with a radiator core, of a shell forming the regular finishing piece f sheet-metal having a front open panel and side flanges ward therefrom, the depth of said sides being sufficient to space the plane of the front from the front plane of the core, bearings mounted on the inner face of the sides of the front, shutters journaled in said bearings and extending across mon actuating means for said shutters, by which they may be simultaneously opened and closed in the space between the front faces of the shell and core. v

5. The combinationwith a radiator core, of a shell forming the regular outer finishsaid core, thereof, and shutters controlling the air to said core, inclosed and operable within the forward extension of said shell. 6. The combination with a radiator core of a shell formin the regular outer finishing iece for sai core, said shell being extended forwardly beyond the core and being provided at its front with an open panel for exposing the air and water tubes, and means for regulating the flow of air through the core mounted and operable within said shell and extending between the front face thereof and the core.

. 7 The combination with the regular outer finishing piece 'for said core and having its front face in a plane spaced forwardly'from the extending rear-' said open panel, and a co v ing piece for sai extending forward open a radiator core,

core, mechanism for regulating the flow of air through the core mounted within said shell and operable within the space between the front face thereof and the core, and operating means for said mechanism arranged between a side of the shell and the adjacent sides of the core.

8.- The combination with a radiator core, of a shell forming the regular outer finishing piece for said core, having its front face in a plane spaced forwardly from the core,- shutters mounted within said shell and operable in the space between the front face thereof andthecore, an actuating strip connecting said shutters, and a bell-crank mounted between the core and a. side of the shell, having actuating engagement with said strip.

9. The combination with a radiator core, of a shell forming the regular outer finishing piece for saidcore, formed of presse sheet-metal and incasing the core and sides and top thereof, and having a front face with an open panel, the depth of the sides of the shell being sufficient to space the front thereof forwardly from the core, shutters extending across said open panel within the front portion of said shell, a pair of bearing str ps for said shutters mounted interiorly upon the front of the shell respectively at each means for said shutters. Y

10. The combination with a radiator core, of a shell formin the regular outer finish- 5 core, formed of pressed sheet metal having a front face with an open panel and side flanges extending rearwardly therefrom, the depth of said sides being sufficient to space the plane of the front of the shell from the front plane of the core, and shutters mounted on the inner face of sai shell adapted in one position to close said panel and also to swing in the space between the shell and the coreto open said panel, the shutters in their open position presenting a front edge having a reinforcement.

11. The combination with a radiator core of an automobile, of a shell forming the regular outer finishing piece for said core, and shutters carried by said the passage of air through said shell to the radiator core. 0
